Creation encompasses the whole process from start to finish, (wherever you start, wherever you finish). As i see it Capture is one part of the creation, the Capture being the stored data in the raw file or the unprocessed negative.

Actually, creation is horribly inaccurate. A photographer creates nothing. The scene already exists, the photons of lights reflected off the scene already exist, the camera already exists, etc. Even the editing of an image isn't creation, it's manipulation of information that already exists.
